I am sure a lot of you have already visited the official common core site. But have you taken a look at appendix A, B and C? There is some valuable information there and it is a good idea to become familiar with these documents and to begin using them. You can learn about text complexity and glossary of key terms in appendix A. In appendix B, you will find a wealth of information about text exemplars (stories and poems to use) and sample performance tasks. It is a great way to get started on common core tasks before branching out to write your own. In appendix c, you will find samples of student writing. This is a wonderful resource, but let me warn you some of the writing is really, really good.
